Poor health is generally believed to cause political passivity. Prior studies that satisfactorily acknowledge the causality problems involved are mainly limited to considering turnout and the U.S.A., so we lack knowledge of how non-electoral participation is affected in other countries. This article considers Sweden, characterized by a generous welfare state and an extensive public health system. Using unique panel data, which allow more thorough analyses of causality, poor health was found to have a negative effect on voting but not on non-electoral participation. By primarily focusing on other countries than Sweden and the U.S.A., it is a task for future longitudinal research to show whether the belief that poor health lead to political passivity is incorrect—or whether Sweden is an exceptional case, due to the barriers to participation being particularly low there.
